Nilo® K Kovar® K 1.3981 Alloy K pipe N08825 Round pipe 6x1-26х2mm (size : 6 x 1mm, length : 1 meter x 10 st/pc)

Length tolerance: +/-2mm- Production time is approximately 2-3 weeks. - Preparation for shipping takes 2-3 business days. - Delivery duration varies based on the parcel service; please consult our FAQ for details.Kovar® is a nickel alloy made up of about 54% iron, 29% nickel, and 17% cobalt. It stands out for its very low thermal expansion coefficient (around 5 ppm/K) and outstanding toughness. This material offers solid physical and mechanical qualities and is suitable for deep drawing and punching processes. However, Kovar® is not resistant to corrosion in humid or wet conditions and requires an additional protective coating. The 1.3981 grade has a tensile strength of 530 N/mm² and is non-magnetic. It is also easy to solder.You can find Nilo® K tubes in the Evek GmbH online shop.
